Abstract

Abstract An enclosure for through-the-wall or window type airconditioners which may include additional heating and/or humidifying means. The enclosure consists of a one-piece, molded housing or chassis for supporting the various functional elements of the unit and a top and front cover. Centrally of the chassis is a firewall which extends between a pair of laterally spaced side walls intermediate the ends thereof. Suitable mounts are provided on opposite sides of the firewall for the condenser, compressor, evaporator, and other components. Portions of the blower housings may be molded integral with or separate from the chassis and provided with suitable mounts for the evaporator fan motor. Evaporator drain pan areas molded as part of the blower housings provide fast runoff of the condensate from the evaporator. A fan motor support, channelled water pan and lower portion of the fan shroud may be molded integral with the floor member of the chassis. The upper portion of the fan shroud is molded integral with the top cover. Such an enclosure greatly reduces the number of elements heretofore required for window or through-the-wall air-conditioning housing, thus simplifying the manufacturing procedures and reducing the overall size of units of this type, and eliminating the need for decorative covers previously required.
